In trigonometry trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined Geometrically these are identities involving certain functions of one or more angles In mathematics an identity is an equation which is always true regardless of the specific value of a given variable An identity can be trivially true such as the equation x x or an identity can be usefully true such as the Pythagorean Theorem s a 2 b 2 c 2
